Policymakers have to make judgments based on the best intelligence they get.

Putin has a lot at stake here and restoring the relationship with the United States, and there are already signs as Sandy mentioned that he's moving in the right direction to begin to ascertain that their trade with Iran is not used for the production of nuclear weapons.

Look at what the Omar of Qatar is doing, for example - the King of Morocco, Jordan, Bahrain. There are reform movements taking place, efforts to broaden the political participation of the populations of the region.

Intelligence is not a science.

So, I think even in Saudi Arabia there is movement. And we have to remember that over the years they've stabilized the oil price and that is tremendously important for the economies of the world. I think we have no choice but to work with the government of Saudi Arabia.

Over a period of time, I think the popular will in Iran will prevail.

We went into Iraq because Iraq posed a threat to the stability of the region and was engaged in the process of trying to develop weapons of mass destruction and had links to terrorists.
